Reinforcing vibration-damping material and reinforcing vibration-damping structure

A reinforcing vibration-damping structure comprising:

• an object;
• a reinforcement member disposed on the object and reinforcing the object;
• and
• a vibration-damping member disposed on the reinforcement member in a thickness direction of the reinforcement member to suppress vibration of the object,
• wherein the vibration-damping member has a first portion that overlaps the reinforcement member in the thickness direction and a second portion that does not overlap the reinforcement member in the thickness direction and is disposed on the object in the thickness direction,
• wherein the reinforcement member has a reinforcement layer disposed on the object in the thickness direction and a first constraining layer disposed on the reinforcement layer in the thickness direction,
• wherein the vibration-damping member has a vibration-damping layer disposed on the first constraining layer in the thickness direction and a second constraining layer disposed on the vibration-damping layer in the thickness direction,
• wherein the reinforcement layer is a cured product of the first resin layer containing a thermosetting resin, and
• wherein the vibration-damping layer is made of a second resin layer containing a butyl rubber.
